today i when i waked up i notice my mp20 controller box is blinking red . i disconnected the cord and waited a couple of min and plugged it again and it was running for a couple of sec then it will stop again. im going to give t it a vinegar bath today. i do have alot of coralline algae on it and ive had this pump for at least 1yr 1/2. my ? is when i unplug it and it shuts down can i just pull it off with out taking off the dry end?
